Cosmic Shear and Clusters of Galaxies
Y. Mellier, L. van Waerbeke, T. Erben +9
The first detections of cosmic shear signal reported recently by 4 independent groups cover angular scales between one and 10 arcmin. On those scales, the cosmic shear is a signatu…

A Numerical Study of Cosmic Shear Statistics
A. Thion, Y. Mellier, F. Bernardeau +3
We explore the stability of the variance and skewness of the cosmic gravitational convergence field, using two different approaches: first we simulate a whole MEGACAM survey (100 s…

Cosmic Shear with the VLT
R. Maoli, Y. Mellier, L. van Waerbeke +5
We report on the detection of cosmic shear on angular scales of 1.3-6.5 arcmin using 45 independent empty fields observed with the Very Large Telescope (VLT). This result confirms…
